About the company
Our client is a fast-growing technology company.
The role
Raydar is recruiting for this role on behalf of our client. Build and run evaluation and reinforcement learning task pipelines for coding-focused AI models, working directly with external customers from the first day. The role grows over roughly six months from hands-on engineering into leading a small team of engineers.
What you'll do
- Design and build coding evaluations and reinforcement learning tasks, along with the pipeline that produces them.
- Run evaluations of leading AI models against an internal benchmark and a set of representative tasks.
- Partner directly with customers, quality-checking deliverables and shipping to specification.
- Build reinforcement learning tasks hand in hand with customers as the engagement matures.
- Grow into leading a team of engineers over the first several months.
Requirements
What we're looking for
- Solid working knowledge of reinforcement learning, coding-focused RL, evaluations, harnesses, benchmarks and post-training; this is a firm requirement.
- A blend of research intuition and the engineering skill to build tasks and evaluations.
- Prior experience at a data company, or concrete self-driven evidence such as a benchmark you built or a post-training side project.
- High energy, strong drive and a hunger to learn and do as much as possible.
- High agency, a strong work ethic, integrity and an earnest attitude toward learning.
- Roughly 1 to 5 years of relevant experience.
Bonus points
- Research experience at a strong lab or university.
- Interest in starting a company someday.
- Relocating to the Bay Area from outside the region and a deep curiosity about AI.
